so whats the problem??? Well when ever I move the mouse while holding the left mouse button down, or randomly for no reason at all, or while glxgears is running I get static on the screen. Similiar to snow you get on a tv that is turned on but as no signal with cable.

It also occurs when I type to fast, or move a program window around to fast.

So am I the only one with this problem?

any suggestions on how to get rid of this?

I guess I can try the xfree-drm/dri route, but I hate to try it since I was able to get this up and running with very little effort after reading the many posts on the forum about getting these cards to work.

thanks!

I also changed this section in XF86Config-4 (so X starts up in the mode I like):

Code:

# changed Modes to "1600x1200@85 which is supported by my monitor this keeps X from
# guessing the mode to run in, just in case it picks one I don't like
# Also made sure depth was set to 24 (ati cards don't do 32)

I have recompiled the kernel to get rid of the framebuffer support, this didn't fix anything.
I have changed all the fglrx options in xf86config one at a time, still not working.
tried disabling silken mouse but for some reason I can't get it to disable, so I will assume this won't fix it either.

So my next thought is to recompile the ATI drivers with a very conservative CFLAG setting.

My last post shows how tired I am....I actually thought changing CFLAGS would make a difference on a binary driver.

So I am moving on to other things to see if I can make this work correctly. I will try a few more things and then I will have no choice but to go with xfree-drm, and xfree radeon drivers and hope for the best there.

I disabled accelation to see what I got, that removed all of the static on the screen. The problem there is when using the scroll whell on the mouse it scrolled as fast a snail. Not going to work for me.

So I re-enabled it, and then disabled DRI. That has severely decreased the static but it still shows up a bit here and there. At least the mouse scrolls fast, my guess is as long as acceleration is on silken mouse is loaded.

this is much better but now I have no 3d support, so I will have to keep trying.

I've had problems with ati-drivers-2.9.13 and instead use ati-drivers-2.9.8. 2.9.13 locks my computer up (completely) when I play Neverwinter Nights (always 10 sec into the game). 2.9.8 doesn't have that problem. It does, however, want to hide my mouse behind the OpenGL screen layer for long periods of time (which is annoying when attacking moving targets). xfree-drm is just too slow for NWN (2 FPS). 2.9.8 gives me 40 FPS.

still haven't had a chance to downgrade the ati driver. Life is like that......tried quake 3 and I get 40fps in the game which is pretty bad compared to the happy 125fps I get with the mobility 7500 in my laptop. I will continue to work with this and post results to this thread.

Hi, I had the exact same problem ( I believe ) a few months ago, nothing I tried worked. So I got used to it and thought no more of it...until the day came when I by accident deleted the contents of /user/lib... and was kind of forced to do a reinstall.

When I was at it I also bought a new HDD ( this is the good part! ) this made me disconnect all cables and stuff. When I later installed everything I noticed how the snow was gone, not a trace of the annoying stuff. That was 2-3 months ago, and today I rebooted for the first time..( had to cut the power... ). I noticed that the tv-out cable wasn't connected to the tv, so I plugged it in and thought it would be nice to watch some stuff on the tv. When I later started the computer IT happened..the snow was back! So naturally I concluded that the tv-out was doing something weird to the card. I unplugged the cable and rebooted. Voila! no snow!

Strange, I don't use the TV out. I did a new install last night, I haven't been using Gentoo lately because I am to busy to work on this problem. After the clean install I am still having the snow problem when running anything that is hardware accelerated.

I am getting 1300 - 1500 fps with this card using glxgears, I would think it could do better than that but I am not sure. So if someone could give some stats to compare with I would appreciate it.

Obviously the installation steps have changed since I posted all of this. If I find a solution to the snow problem that works for my situation I will post it here.
